To all 'whom it muy concern:

Be it known that l, `WILLIAM F. Knien- BAUM, a citizen oi' the United States, residing at Newark, in 'lhc county of Essex and State of New Jersey,.have invented new and iisel'ul Improvements in Feed-Water Regulators or Controllers, oll which the following is a specilication.

This invention relates to a boiler leed pump regulator and has beendevised to control and maintain the discharge pressure in excess of the pressure carried in the boiler' in accordance with the requirements el' the pump under certain conditions The present invention is el' regulators or automatic controlling devices which are operated by the initial or boiler pressure acting upon a piston and which actuates a main valve to open the same, the admission ol' the initial or boiler pressure to tie piston being controlled by an auxiliary or secondary valve, which in turn is operated by two diaphragms subject tov any variation oi' the initial or discharge pressures desired to be maintained.

The objects el' this invention are that type ol' to prol automatieally maintain an excess water discharge pressure o' say about fifteen pounds above the initial or boileil pressure at whatever point the latter may be, and to provide a soll-contained. pressure controlling device which is oi' simple construction and devoid ol' stufllng boxes or adjustable devices and thus avoid outside means for tampering with the adjustment and operation el' the i ,(fulator or controlling device.

The accompanying drawing illustrates a transverse vertical sect-ion oll ,a pressure reguing device embodying the lator or coi'itroll ,features oi' the invention, and referring thereto the numeral l designates the body portion of 'the valve, apertured and threaded at one eild A to receive an initial pressure supply pipe, as shown by dotted lines, and also threaded and apertured at the other end B to receive a continuation of said pipe beyond the valve, the said body l. having a partition l separating vthe apertured and threaded ends A .and B and forming at its under side a horizontal seat lb for a valve 11. This vlave l1 has a stem 11a projecting above and below the same, the lower port-ion of thesteni being centered by a plug 13 and surroundedfby a coiled spring l2 which supports the weight of ol operation..

normally resting or passage '26 in the with ing communication pressure receiving tending vertically th munication with the inwardly extending said channel. 2O to tending through a partition 3 at a suitable distance above the )artition la.

On the upper end oi the bo mounted, the said upper extending through tl opening 2b, and inthis opening is fitted a screw-threaded seating plug through the medium valve and also through valve casing 2. The channel The upper portion of the stein l1Ct is centered and engaged by a piston shank 3a movably eX- b in the body l y l of the casing 2 is portion of the body piece or casing 2 being connected by means of ie top piece or casing 2 upper valve has a central boss 2u at its lower end which dowii'lvardly into the top of the the piston 3 is mounted ln the center of the ece or casing 2 and also ie boss 2a is a threaded l having a pasending 'centrally theresurroundingl the upper eX- or passage and projectthe plug is a raised seat lt is obvious that instead of threading and screwing tno plug Ll'iiito place as above could be otherwise secured in position, and to regulate the peneinto the top piece it is provided with a circumferential flange 4b bear against the boss 2a to make a sealed joint.

centra-l enlarged passage Above the plug 4 a 1S is formed in the asing 2 and is provided spider 18 having opentherethrough. Vithin this passage 18 a controlling valve 30 is lt has a depending stem or shank a extending downwardl ter ot' the passage i8 r through the cenand the spider lS'and on the seat la over the bore plug el. The upper end of the top piece or upper casing 2 is formed an annular semi-circular channel 20 havwith the initial su l end A of the vglDvb of a iassage 20a ei;- rough t e body l of the the top piece or upper 2,0 also has cornpassage '18 by means of ports 2Gb running from e passage at intervals.

On the up ier end of the top piece or upper casing 2 a diaphragm cap is secured, the greatest diameter of this cap being at its lower extremity or at the portion 'thereof that is secured to the top piece to form a diahragm chamber 5a of which the channel 2O 1s a part. This diaphragm chamber is horin .Zontally divided by a partition or septum 6, so constructed. as to perrnitof the downward movementl ot diaphragm -7 and upward movement el the opposite diaphragm 8, and having raised faces to secure tue diaphragme 7 and 8 at their edges, thus making a sealed joint between the channel 20 in top casing 2 and diaphragincap 5. rihe partition or septuin 6 is provided with ach-cular groove 6" extending around the saine and with a series of apertures 6c extending therethrough said partition or septum having a port 25 leading irom circular groove@vn into the space between the two diaphragins. A diaphragm washer 9 is disposed between the diaphragme 7 and S and operates as a movement transmitting means for one diaphragm with respect to the other, and has a reduced portion nio'vably extending through an opening in the partition or septum 6. The washer or motion transmitting nieinher il engages hoth diaphragme, and, has an upper contacting area of less diameter than the lower contact ing area the lower increaseddiainetrical por# tion of the said washer or nicinher hearing'ozu the diaphragm S and the upper reduced contacting area of said'rnenioer engaging the under side of the diaphragm 7. The valve 3() is also normally held in contact with vthe under side of the diaphragm 8, and surrounding the shank 30a ol the said valve isa spring l() which operates to hold the valve against the diaphragm 8, said spring engaging the valve at its upper end and the spider 18 at its lower end. The diaphragm cap 5 gradually reduces in diameter towards its upper end, and extending therefrom into the upper portion or"I the diaphragm chamber 5 directly over the center of the upper diaphragm 7 is a pendant 17 having its lower terminal above or out ot Contact with the said diaphragm 7, and extending centrally through the pendant and `the portion of the diaphragm cap immediately above is a bore l7L that primarily communicates with an upper inverted conical cup ,lb in the upper end ol" the said cap .5.

n the up er extremity of' the here 17'LL is a tubular bus iing lll projecting upwardly intothe cup 17h, having a hole ol sin-aller {llame-- ter than bore i7 to restrict the passage of water and prevent pulsation ol the dief phragin resulting with each stroke of the pump, which would soon crystalline the rnetal ol' which the (.linphrao'ms are coinposed and cause tlicni to break. The pro gection of the bushing le above the. bottom t' the inverted conical cup l7b is to ohviate eiaese the lodginent oi any sediment on the upper end of said bushing, and to assist in overcoming this disadvantage said upper end of the bushing is rounded as shown. in view of the small bore of the bushing any tendency to pulsation of the diaphragm immediately low in response in the stroke of the pump will be dissipated. Over the upper end of thediaphragin cap 5 is a hollow nut l5 in which is.'ltted a thinible 16 in which aopipe 2l, shown in. dotted lines, is secured and connected to the water discharge from puin i. ln the diaphragm cap 5 is located a tell-tale port 22 communicating with the circular peripheral groove 6b in the dividing partition or septum This groove 6b coinniunicates with the space between the diaphragnis 7 and 8 by the ort 25 to which reference has been herein clore made. ln case there should he ru )ture of either of the diaphragme, stearn will enter the space between the saine and will enter the port 25, circular groove 6b, and from the latter, ass to the atmosphere by way of the tellta e port 22, so that by virtue of the said tell-tale port such rupture or other breakage will beindicated exteriorly of the regulator, This telltale port serves an additional function in that it presents the accumulation oi pressure in the space between the two diapl'iragms -and thereby prevents the regulator from becoming inoperative from such cause.

The member 9 may be properly termed a washer having differential contacting areas,

element be use it will he understood that the saine result may be obtained by using diaphragme of different diameters. By the use of the member 3 or washer, there is less liability of rupture the diaphragnis, but an obvious substitute for this member would be the use of diaphragme having different diameters.

The valve 3() serves as an auxiliary va ve and will be referred to by such term in the claims hereto appended. lt will also he noted that the piston il is considerably larger in area than the mein valve 1l co-4 operating with the artition lL between the respectively. The urpose of this dill'crence of' area is to insure t isplaceinent of the valve 1l from its seat by the piston when the latter is operated, will he hereinafter set forth. The lower wall of piston 3 is provided with a port 29 oi reduced diameter and in the partition 3" ports 28 are also provided, the purpose olE ports 28 being to allow the pressure under piston 3 to equalize with that on the outlet side oi' the valve. The piston is made smaller in diameter than phainher 3 and is provided with a snap ring te prevent steam passing between piston 3 and wall of cheniher 3.

The operation oi the device is as follows:

opposite ends or inet and outlet A and B and though it is referred that this particular 10 u ward movement of the 20.Wardly and depresses the 8 t rough the meriuln The initial su ply pressure enters at A and passes .throng i the passage 2Oa to the channel. 2() and exerts its influence on the lower dia liragm S, raisin both dia hragms 7 and of tie member or Washer 9 between the said diaphragms and permitting the auxiliary valve 30 .to open, the spring 10 o erating to force the valve upwardly or to fiillow the diaphragms. The auxiliary valve 30 lli ts the stern 30*EL clear'of the raised seat-il1 and uncovers the bore or passage 26 in the plug 4 and permits the pressurefto pass downwardly from the channel 2O through the i ports 20b into the chamber 18, through the openings 18h' of the spider 18a and into the piston chamber 3 above the piston 3 through' the bore or passage 26, above noted. By this means the piston 3 is forced downvalve 11 from its Aseat 1b formed 1n 'the artition 1a, the downward movementv of t e valve 11 being resisted by the initial supply pressure and the spring 12. The release of the valve 11 from 25 its seat as just explained establishes comexcess of f the piston 3 to escap pressure.

'5.5 of the initial or boiler pressure.

is frequent matically increases or munication between the inlet and outlet ends of the valve, and the fluid is permitted to pass from A to B and thence to the pum As the Apum compresses its discharge to an teen pounds above the initial supply pressure it forces the diaphragme 7 and 8 downwardly a'gainst the said opposing initial supply pressure and seats the auxiliary valve 30, allowing any rassure above e throug ports 29 and 1 28 and equalize with the pressure on the under yside of piston 3 as heretofore explained. At the same time the initialsupply pressure, assisted by' spring 12, seats valve 11.

4When the pump has compressed its dischar e to 15 pounds in excess of the initial supp y pressure the steam throttle, or high pressure stop lvalve on the pump should be opened Wide, and the regulator' will then *'45A automatically' maintain the said fifteen pounds Water discharge pressure in'exeess of the initial supply pressure regardless of the increase or decrease of the said initial supply If for any reason the initial or oil'er pressure should fall or increase, the

" improvedl controlling device will automatic- .ally maintain an excess of fifteen pounds of A4water discharge pressure over the initial or boiler pressure or over any fall or,increase ln other words, the water discharge pressure autodecreases in proportion to the increase or decrease ofthe initial' or boiler ressure. For illustration, if, as y the case, on naval vessels where -the initial pressure is two-hundred fifty prounds While at sea, the discharge pressure om the pump would be two-hundred 'sixtyiv'e pounds; and lwhen in port or at anchor villustration. is given to show t .the mean effective phragm 2.40 square with this difference between the two mean effective areas if there was a pressure of onedrawings, but, in view of the lthe boiler pressure is reduced to eighty pounds, then the discharge pressure from the pump would be ninety-five ounds. This iat the operation is entirely automatic. The excess in water discharge pressurey over the initial or boiler pressure may be varied by changing the diameter of the member -or washer Q, thus changing the mean effective area of one diaphragm. `For illustration, the washer or member 9 at bottom being one and one-half inches and at the top one inch, the mean effective area of the lower diaphragm would bc approximately 3.54 square inches and area of the upper diainches. It is obvious hundred pounds on the lowerside of the one diaphragm it would require an excess )ressure of say fifteen pounds oifthe top ci the upper 'diaphragm to overcome the pressure on the opposite side of the lower diaphragm.

y means of the regulator or controller hereinbefore specified, water and fuel are saved, wire drawing over` the seats of the feed valves is avoided. It will 'The understood that the several parts of the regulator or controller may be secured by means other than those shown, and, furthermore, that modifications may be adopted in the details of construction without in the least departing from the spirit of the invention.

Some ofthe appended claims indicate that the initial or boiler pressure operates on the outer side of one of the dia hragms and that water discharge pressure from apump operates on the/outer side of the other dia phragm. It is believed that it will be clear what is meant by this language. However, it is deemed desirable to state that in the present case Ithe outer side of thc diaphragm 7 is the uppersurface thereof while the outer side of the 'diaphragm 8 is the under surface thereof. lt is believed from the statements just made that it is not essential. that the dia hragms stand horizontally or substantial yy horizontally as they are shown in thc fact that they are thus represented, it is deemed desirable to point out how such language.- applies to the relation shown.
